To L7/Z whom t may concern,.-

Be it known that I, MATTHEW T. (li-IAP- MAN, residing at Aurora, in thecounty of Kane and State of Illinois, and a citizen ofthe United-States,have invented new and useful Improvements in Tube-Tells and PumpingMechanism for the Same, of which the following is a full description,reference being had to the accompanying drawings, in which- Figure l isa side elevation, the tubing being broken and the lower end of theexterior tubing being in section; Fig. 2, a detail showing thedrill-head, coupling, and exterior tubing in section; Fig. 3, across-section online a: x oi Fig. 2; Fig. 4, a detail showing a sectionof the tube and one of the lifting-valves; Fig. 5, a cross-section online i/ y of Fig. l; Fig. 6, a detail in section of the upper end of thetubing, showing the piston-rod in elevation; Fig. 7, 6; Fig. 8, a detailshowing the wings of the drill expanded, Fig. 1 showing them closed.

This invention relates to'deviees for boring a hole for the purpose ofsinking a tube for a tube-well, and has for its objects to enable therod which operates the drill to be utilized as a pump cylinder or tubeby having such rod independent oi' a lifting-rod; to insure the liftingand removal of the water, sand, cuttings, and dbris during theoperation'of sinking the hole without interferingnith the operation ofthe drill; to produce a rotation of the drill-rod and drill without atthe same time rotating the discharge-pipe; to improve the devices fordriving sections of the tubing as necessary, and to improve, generally,the construction, arrangement, and operation of the several parts bywhich the hole is bored, the water, sand, cuttings, and other debrisremoved, and the tubing for the well driven; and its nature consists inthe several devices hereinafter described, and speciiical ly pointed outin the claims as new, for attaining the objects sought.

In the dra-wings, A represents a drill formed of a head, a, andexpansible wings b, the head at the upper part-being hollow, andprovided with one or more holes, c, for the passage of water. This drilland its construction is not a cross-section on line c ,e of Fig. l

' which enters and rits the opening 1n the drill herein claimed, as itis to be made the subject-matter of another application to be filedherewith, and is only shown herein to illustrate a drill in connectionwith the other devices, it being, however, expressly understood thatother forms of drills can be applied ,and used with the devices hereinshown.

, represents ahollow drill stock or stem.

G represents a coupling screw-threaded on iis interior, and adapted toreceive the lower end ol' the stock B, having a correspondingscrew-thread, and the upper end of the drillhead a likewisescrew-threaded, to connect the stock or stem with the drill, as shown inFig. 2. The stock B is made oi iron tubing or other suitable material.

D represents sections of iron tubing or other suitable material, forminga hollow lifting or piston rod. The lower end of the section D stock orstem B, as shown in Fig. 1, which piston may be formed, as usual, ofplates or heads c, between which are elastic or packing rings or headsc.

E represents a cap or stnflingbox on the upper end ol' the drill-stockB, and provided with an opening for the passage of the rod or tube D.This cap at its top or closed endhas an opening, g, which receivesaspline orprojection, f, on the exterior wall of the tube D, by means ofwhich spline and opening the tube and cap E are locked together, so thatas the rod is rotated it will impart rotation to the drill-stock anddrill. The cap may be proel, so that the valve can be raised from itsseat \vided with an interior screw-thread correi of the piston-rodhassecured lthereto a piston,

lll

for the passage of the matter to be discharged through the piston-rod D.The opening in the drill-head a is closed by a flap-valve, d, attaehedto the upper end of the head, as shown in Figs. 2 and 3, and this valve,in connection with the valves in the couplings or chambers F,furnishesthe means for controlling the passage of the water and other materialsthrough the piston-rod to the discharge. The lower section ofthepiston-rod, at a point j ust above the stuffing-box E when the piston isdown, is provided with metal collars h, between which collars are rubberrings t', a rubber ring being also provided around the piston-rod belowthe under collar l1, as shown in Fig. 1,which rings and collars furnisha bumper for striking the stuingbox E and forcing the drill-stock anddrill down.

G represents a dischargenozzle, through which the material raised by thepiston-rod is emptied onto the surface of the ground or otherreceptacle.

H represents a casing located around the piston-rod D in such manner asto be free to rotate on the piston-rod or allow the pistonrod to rotatetherein. This casing II is provided with a suitable opening, H', toreceive the end of the discharge-pipe G.

I represents stuiiing-boxes-one at each end of the casing II-between theface of which and the end of the casing is a packing, j, of suitablematerial, and, as shown, the end of the lower stuffing-box rests upon acollar, Z, on the upper section of the piston rod or tube D, whichcollar is secured in anyflrm manner to furnish a support that will holdthe casing II from slipping down on the rod. The interior of the casingH, at a point in line with the discharge, is enlarged somewhat to form achamber, and the section of the piston-rod within this casing at apointin line with the enlarged portion is provided with a series of openings,7c, to allow of the passage ofthe water and other material from thepiston-rod in the chamber and out at the discharge.

J represents a head having a central screwthreaded opening to receivethe upper end of the piston-rod having a corresponding screwthread. Thishead J is provided with a ring or eye, J", for the attachment of a ropeor other lifting device by which the pisto`nrod can be raised. The ropefor raising the piston-rod passes up over a pulley or wheel located on aderrick or othersupport, and thence down to a windlass, as usual, bymeans of which rope and windlass the rod can be lifted to the desiredheight, and then dropped by allowing the windlass to run free. This partof the apparatus is not shown, as it may be of any of the usual andwell-known forms of construction.

In use the hoisting-rope is to be attached to the ring J', or connectedin some other sutable manner with 'the upper end of the combined liftingand piston rod D, and this rope is to be wound on its windlass in theusual manner, raising the rod D the required height, when the windlassis to be tripped, as usual, allowing the rope to fall, causing the drillto strike and be operated in the usual manner. The rod D can be raiseduntil the piston on its end comes in contact with the under face of thecap E, when the further lifting of the rod will raise the drill-stock Band the drill attached thereto, and the weight of these part-s and therod, when the rope is released, will cause a rapid descent, by which thedrill will be forced into the resisting material which is to be removed.

The operation of .drilling at the same time causes the removal of thewater, sand, and dbris cut away through the pump or piston rod D,through the raising and dropping of' such rod, in connection with thevalves d and the valves in the chambers or couplings F. The elevating ofthe rod opens the valve d, allowing the water, sand,A and other materialto pass through the openings or 'channels c into the chamber of thedrill-stock B above the valve d, and the descent of the rod D closesthis valve d, and at the same time opens the valves in the chambers orcouplings F, allow ing the water, sand, and lother material to pass fromthe chamber in the drill-stock B up through the drill-rod D above thevalves in the chambers or couplings F, and the valves in these chamberswill be closed bythe ascent ofthe rod, holding the water, sand, andother material which has passed the valves above such valves. Thecontinued operation of raising and dropping the drill or piston rod Dopens and closes the valves, as above described, forcing the water upwith the sand and other material and discharging it through the pipe G.

By providing several valve-ehambers, F, each having a valve therein, theaccumulation of too much sand and dbris on the lower valve will beprevented, as the lower valve will onlyr support such portion of thesand and dbris as is being raised as will be contained in the spacebetween it and the next succeeding valve, and as many of thesevalve-chambers F and valves d are to be provided as may be required forthe work to be performed. As the hole which is being bored is sunkdeeper additional sections of the rod D are to'be added to suit theincrease in depth. The water, sand, and other material raised throughthe hollow rod D pass out therefrom through the orifices 7.', and thenceinto the chamber in the casing Il', and out at the discharge G. Thecasing II being supported around the rod D and independent of that rod,it will be seen that the rod can be rotated to cause the drill to actwithout affecting the casing and discharge, which remain stationary; andas the drill-stock and the rod D are connected, the drill will berotated with ,the rod, so that its point will not strike repeatedly inthe same place.
